Paxton's 150 Fuel-Pump Kit - Fuelish Pleasures

1/21The Paxton Street/Strip 150 electric fuel pump has a free-flow rating of 140 gallons per hour and is factory set at 16 psi. The pump works with either gasoline or alcohol. The pump's aluminum base has provisions for AN-6 inlet/outlet fittings, thus making for easy installation and serviceability. The kit includes a pump mounting bracket along with a dual-outlet-port, adjustable fuel-pressure regulator.

As savvy car crafters know, for an internal combustion engine to work correctly you need to blend the proper amount of air and fuel to promote proper combustion. Drawing in the correct amount of air usually isn't a problem, but delivering the proper amount of fuel can sometimes be difficult--especially during high-rpm operation. Further complicating fuel-delivery matters are high-output race engines that gobble fuel rapidly or street/strip engines that use a supercharger or nitrous oxide.

Over the past few years, you've been reading about Project Cheap Street Chevelle. We transformed an old '70 Chevelle into a potent street machine by way of a hi-po 355ci small-block, a 3,000-rpm torque converter, a street/strip auto trans, and a set of 3.73:1 rear gears. The fuel-delivery system consisted of a stock gas tank, a better-than-stock mechanical fuel pump, a rebuilt Quadrajet carburetor, and an NOS Super Power Shot nitrous system. During normal cruising, the fuel pump adequately supplied the proper volume of fuel flow. However, at high rpm the pump was inadequate, allowing the

Q-jet's fuel bowls to run low--eventually starving the engine and causing it to surge and misfire. Moreover, when the nitrous oxide was used, the problem was even worse. Excessive surging (caused by the engine leaning out) can quickly destroy an engine.

To remedy the Chevelle's fuel-delivery woes, we wanted to install a new electric fuel pump along with an adjustable fuel-pressure regulator. However, with so many sizes and gallon-per-minute (GPM) pumps available, we weren't quite sure what would be enough for our application without it being overkill or super-expensive. Thus, we turned to Paxton Products, which has a new line of electric fuel pumps and adjustable fuel-pressure regulators specifically designed for street/strip use. After analyzing our Chevelle's needs, Paxton recommended its new Street/Strip 150 Fuel Pump package (PN 8002212), which would easily support our current level of horsepower--and would also be adequate enough to support more power if we decided to further hop up the engine at a later date. The pump and regulator combo are compact, which makes them easy to install on most musclecars; also, they are an affordably priced package, making them easy on your wallet. Follow along as we show how to install an aftermarket electric fuel pump and regulator.
